Can you alter your subconciouse (emotional drives/motivations) with lucid dreaming?

[intuitionlink2]

I asked a similar question here before but i don't think i gave enough detail. I want anyone who can or has a experience it to provide me a guide on how to alter my subconscious drives/ motivations vi lucid dreaming. I basically took a gap year and wanted to spend the year building muscle and achieving goals e.g. getting a drivers license. but that was last year and i failed to do any of what i set out to. I have mild depression so that may have contributed to my downfall and me wasting over 12 crucial months that could have done me wonders and possibly changed my life for the better had i utilized it or mastered the subconscious manipulation i aim for. i want to for example. 1. instead of having an urge/motivation/ emotional drive to do things such as watch tv, sleep in, eat junk food or day dream too much to alter these drives to doing things that are more productive for me. So instead of having this powerful urge (obviously rooted in my subconscious because consciously i don't want to do these things but can't really fight the urge) i would have a powerful urge to lift weights or do ab exercises (which i intentionally chose to make my subconsciousness to make me do). But is this possible? have i put all my eggs into one basket? or if you have successful achieved this or have an idea or suggestion how to achieve this successfully i would really appreciate it thx.
