Wherever you decide to put your energies, the key is to become more valuable to your current employer, customers, or clients. You do that by getting better at solving their problems, delivering products, and adding services that they want and need.
You may need to get more training, develop new skills, create more relationships, or put in extra time. But the responsibility for getting better at what you do and how you do it is totally yours. Always seek out opportunities for more training and self-development. If you need an advanced degree or some kind of certification to move up in your chosen trade or profession, quit talking about it and go get it.
