Stress almost seems inevitable until we have several pillars stationed (like time management) to ensure we get a grip of ourselves and deliver optimally.
Fear of the unknown in trying out new things is one of my main triggers to procrastinate and the exhilirating feel to meet a deadline might have it's adrenaline and drive but maybe not worth the stress in the long run.
For me, I workout to keep fit, I practice doing some jobs in a haste especially mine then I set an earlier deadline from the clients and work towards it which eliminates disappointments yet keeping the rush I most times need to push forward.
This is great, setting your own deadline.
