Attitude defines champions


Human Psychology: fear of losing constructs negative thoughts in mind!


Jahangir khan and Jansher khan could possibly the two best player ever produced by squash sport’s world. They were not directly closer relative, but did belong to same ethnicity of Peshawar, Pakistan. Two decades (80’s & 90’s) world has seen unforgettable and unbelievable dominance of both great squash players. World open and British open is two of the most highly rated events of squash. Jahangir Khan won 6 World Open and consecutive 10 British Open titles. Whereas, Jansher Khan claimed 8 world Open and 6 British Open titles against his name.  To give glimpse of an idea about the greatness of two players, I could consider them like today’s two greats of Long Tennis; yes you are right I am talking about Roger Federer and Rafael Nadal (I would had prefer it to match Jahangir & Jansher’s supremacy with Roger Federer & Petsemparas, but due to Rafael and Roger rivalry, I do prefer to give their names in comparison).  

There are two great achievement of Jahangir Khan, which may lead him as arguably the greatest of lot and all time best in squash world. First, his 555 consecutive wins, it was started at the age of 17, when he won the World Open title first time in 1981 against Australian Geoff Hunt. His unbeaten winning streak was at last ended in 1986, when Ross Norman beats him in World Open. The second achievement is might be more astonishing then first one is that winning the International Squash Players Association Championship without losing a single point. OH! My Goodness, could it ever happen again in any sports, please do let me know if anyone of you observed such achievement by any other sport man. I think the aforementioned astonishing achievements of Jehangir Khan make him arguably the great player of all time in sports history and marked him as a truest champion of all time that a world would never forget until it lives.

But as for every beginning there is an end, for every rise there is decline, finally Jahangir Khan retired from world of squash as a player in 1993. This article is basically about the human psychology which I observed again today; when I was watching world open squash final of 1993 between two greats mentioned above. It is human nature that when it smells or fears defeat, it starts to construct negative thoughts in human mind, which in actual leads him to defeat. There have been many occasions in Jehangir Khan’s sporting career, when he may fears a defeat before it actually happened; but as a true champion whenever human psyche started to construct negative thoughts in his intellect he suppressed it to overcome defeat. In that 1993 world open squash final, when Jansher Khan started to dominate, Jehangir Khan negative constructs were obvious by his apparent behavior. He starts complaining to referee about the “let & stroke points”, which went against him. At that time I realized that how the fear of losing, gets construct negative thoughts in one mind and how it ultimately results in actual defeat. 

In every part of life, the fear of losing, smell of defeat & desperation may result in to start constructs your negative thoughts & believes, but as a true champion you would have to suppress those negative constructs to get ultimate success.

How to alter default boot sequence using grub2 boot loader

This brief tutorial focuses on how to edit grub2 in order to change boot sequence on systems containing more then one OS. Grub2 is second generation boot-loader, going through rapid development and Linux proprietary introduces enhancements & fixes every known then to optimize the progressive grub2 boot-loader. Regarding alteration of boot order, Some tutorial out there on different webs suggest to assign a appropriate digit (0,1, or 2 depending on the desired location of boot option) to variable GRUB_DEFAULT located at /etc/default/grub. However, it does not work out for me and in any case it’s not the proper way to alter boot order. Following is the simple and appropriate way to change boot sequence.

Step 1.   To edit grub.cfg, you must have sufficient privileges or root privileges, so Login to root user.
[AnyUser@localhost ~]$ su -         //Switches to root user     
Password:                                                         //Enter root password

Step2.
[root@localhost ~]#  cat /boot/grub2/grub.cfg |grep Windows    
//mentions the exact menu entry for windows 7

Result:
menuentry 'Windows 7 (loader) (on /dev/sda1)' --class windows --class os $menuentry_id_option 'osprober-chain-32C8C533C8C4F5DF' {



[root@localhost ~]# grub2-set-default "Windows 7 (loader) (on /dev/sda1)"                       
 // Sets default option as window  menu entry

[root@localhost ~]# grub2-editenv list     // Verifies the requried default menuentry

Result:
saved_entry=Windows 7 (loader) (on /dev/sda1)


[root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfg   
//Construct the updated grub.cfg

 

After login to root user follow below steps to set default option to fedora.


[AnyUser@localhost ~]$ su -              
[root@localhost ~]#
cat /boot/grub2/grub.cfg |grep Fedora
[root@localhost ~]# grub2-set-default "Fedora Linux"
[root@localhost ~]# grub2-editenv list
[root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfg

  
Note: Kernel update might causes to revert any changes made to /boot/grub/grub.cfg and then the same procedure had to be followed again. To get rid-off such repetition one must had to change the default menu entry at /etc/default/grub2/grub (i.e set GRUB_DEFAULT = Windows 7 (loader) (on /dev/sda1)).
