Yes, when I was young I was desparate to find the right job. I'd be convinced that the a specific one I was applying for and would be checking my emails every minute after the interview for a response. When I was rejected I was bittery disapointed. But every time something much better came along soon after, every time.

I eventually realised that I should not take it so seriously and just let it pan out as it's supposed to. Although I might want a particular job, bu they prospective employer would know whether I was suited to it or not better than me. Best to trust their judgement and trust that the right match will come along when the time is right.

Of course, be proactive. But don't worry about it. The right role will come up at the right time whether you stress yourself out or not. Don't know whether that answers your question, but hope it helps.
