It is desirable to be successful, but it is also important to recover from a failed step.
Your special life will have the lowest of the low and highest of the high. Do not expect to live a normal life. Period.
The more you worry, the more you elongate your suffering, the more time you need to heal. Have patience and all the suffering will disappear.
It's not a failure, but an opportunity to improve.
Once you get the thing you want, you just want to get something else. Does it mean that it is futile to have desires? No. If you can flow with the flow of the desires, you will never feel less.
Kicking out your worries won't solve the problems, BUT it will help you to focus better at solving those problems.
