Because you have long term goals and you are feeling you aren’t going anywhere, first of all, accept that you need to be a rethink on how you are working. As if you are passionate about your work and working really hard but still feel stuck its time to see if what you are doing is productive and towards your long term goals.
Being productive means the tasks you are performing are towards your long term goals, then only you will get satisfaction from your work. And unless you won’t be satisfied you won’t be productive.
To get satisfaction, keep a check on how you are spending your time at work and at home. Are you actually being present at what you are doing or just going with the flow? To become present, take hourly breaks. It could be just five minutes break and during this break, get away from your desk, walk around and do one minute of breathing with closed eyes. Ask yourself a question, what task would boost your productivity and then get back to the work with a clear agenda.
This is a small but effective exercise, try it.
