First of all, there is no such thing as a wrong profession. All professions have equal opportunities. You need to know how to tap new and existing resources safely, efficiently and effectively.
If you can learn, then it is possible to grow. You have to find the right way. There is no need to change your profession. Be patient and look for ways to succeed. If you have the potential, you will rise and shine.
Secondly, if you are really adamant, it is never too late. You must know that “when you wake up, this is your morning”. You can start your new career at any time. Age doesn’t really matter. You know, at 35, Jack’s Ma was a schoolteacher, and at 33, Harrison Ford was a carpenter.
