I know this feeling too well. I made the experience, that when you make progress and still not feel satisfied, there is something else bothering you. For example circumstances in your life that are not like you want them to be or things you keep in your mind that needs to be thrown out. It can be subtle sometimes or deep in our consciousness.

Try to look at your life and your life circumstances and see what you are satisfied with and what you are not satisfied with. Maybe it's your job, unfinished projects, family, friends, love, the place where you live or you maybe lack of something specific, that you wanna to accomplish. It can often be things that we don't expect.

Only when you know where the problem is you can work on it. I hope you will be able to find the source and feel more comfortable over time on the path you are going.
