Doing your best to have a good feel about it, not judging yourself, and play sounds like a good way to get started. That brings back the motivation and passion.

When it comes to practicing, here are some pointers :

Be clear on what you want : What is the end result you will start practicing for. Write down some goals in the short and long term (goals make you 407% more efficient)

Get organized : It is great how much more efficient one becomes when your practicing is organized. Write down a practice schedule on paper , and change it up once in a while. It helps holding your focus.

Implement : You probably know ****loads of stuff, so practice using the stuff you have learned. When you have done this for a while and just want to play for fun, you will see that your options have expanded. This keep it fun, and motivate you by seeing progression in your skills.

Rock on man
