It's challenging to answer your question without more details. What do you mean that your "company cannot support" your planning?

If you mean that the company does not have a career path for you, that's ok. If you want to advance at that company, the way to do it is to take initiative and do jobs that you have not been asked to do. (Bosses love that!) Then, after you've been adding extra value and taking initiative, ask for a promotion or salary increase.

You might also ask your boss "How can I perform to make sure you get promoted?" I guarantee your boss will love that too. Then, when your boss is promoted, you get promoted to his job.

One thing that is VERY IMPORTANT in your career is your ability to ASK for what you want. Don't ask, don't get.
