I agree. Find a LQS with classes and a guild or quilting group.
Pick a pattern you really love and fabric you can't resist. Even if it isn't a beginners quilt [though this might help.] If you are in love with it you will finish it faster. Doesn't matter if it is a crib size or California King.
If you aren't in love with what you choose ... like you buy cheaper fabric you aren't wild about and pick a simple but not inspiring pattern you just might want to give up.
I machine quilt. I don't believe you need an expensive machine. Heck, the FeatherWeights only sew straight seams. You just need a well maintained machine.
If you go to a group you may find the members will willingly share their stash with you. Some will give you extra tools they have. Some groups even supply all the fabric for charity quilts.
It doesn't have to be expensive. Consider it cheaper than mental health therapy and healthier than many other habits.
You will find the community of quilters to be awesome.
