Treat it as a hobby. Spend money on tools you may only need for a single project. Experiment. Take your time. Watch youtube videos of other makers to scratch your itch, when you can't (or don't want to) actually do it yourself. Appricate the beauty of enginerring around you. Enjoy the process.
Just start. Either you gain a new fulfilling new hobby, or you satisify your urge enough, and stop being crazy.
