Our mind with our brain is an energy force helping us in the development in our program ,in our career development for meeting the challenges of the present age & in every areas there is a last stage of competition whether it may be a science,technology ,literature,drama,art, painting,fine arts, music, dance & every certain areas.

If we remain little back in our performance such individual gets mentally disturbed creating a tension,worries,& frustration . It is not a healthy practice as in such cases individual may get a target of phobia . 

In order to get avoid mental stress they have to develop the mind with the will power,faith & if necessary thru take recourse to philosophy , religion ,meditation, & breathing practices .

Certain individual while getting up in the morning , they should calmly & quietly  take rest for few minutes in the bed & any ideas disturb the mind during the period of rest they should pass their mental idea as a passing phase .The same practices such individual should follow during the bed time . Besides while leaving for their working place such individual should leave the place in a very smiling mode . With this practice such individual may get relief from their stress & they may come out with the success in their competitive range.

This is my personal opinion
