If you're suffering from burnout, yes.<br />
Short-term solution - take a vacation.<br />
Long-term - Cut your work hours to free up either more hours in a day (eg. 6 hours a day instead of 8) or more days in a week (eh. 8-10 hours a day for 4 days a week instead of 5). Take good care of yourself. Eat right, exercise regularly, drink plenty of water, participate in some mental and some physical activities of interest to you regularly with friends, rest well. And include some personal quiet time in your daily schedule to let yourself relax and get in touch with your carefree side.
Burn out is possible at any age. What do you do?
get a grip
Athletes often retire at 30, so it makes sense that anyone with a physical job would become tired around that age too.
Hell yeah, man !
30 is a mans prime, you shouldn't feel old.
