I've found that there are 2 secrets of relative happiness:
do not seek to have everything you want but seek to want everything you have
life it's tough - it doesn't matter how hard you can hit (good you are, personally and professionally); it will always hit back harder. it matters how much you can get hit and still be able to move on.
After all it's all a walk in the park and there are more important things than bits and bytes, and practices and stuff. Just enjoy all experiences as they are and fight back as much you can.
