A recent challenge has been overcome, and you can now focus on a new challenge.
It's never easy to begin a fresh challenge. Especially a genuine challenge that will see you testing your knowledge or facing up to something that you have avoided for far too long. Do it the proper way: research and professional advice. That way, you know that you'll be off to a good start, and you'll avoid picking up bad habits or bad information right from the beginning.
There isn't a perfect career. There is no job that will provide everything you need to be happy and satisfied. Free yourself from the idea that you can only be happy if you find the perfect job.
