I like this quote by Bukowski:
>If you are you going to try, go all the way.
With regards to roam or any note taking tool, try to look up how power users are using it. Many users freely share their work flow. I wouldnt recommend buying a course or if you can afford, go ahead.
Try to set it as homepage. It should be the first thing that you should open. Learn to capture small tidbits of information. And mark a time of calender weekly to tidy up your notes.
Try this for four weeks, you will notice that it really helps in organizing thoughts in your brain. Ymmv though.
