I encourage you to give it a rip. Making your own music can be joyful--and a bit maddening. I play the guitar and have for 40 years now. I'm probably above average. I've paid all my meaningful bills doing something else I'm much better at than guitar. Never had a lesson. My son has played the drums for the past 10 years. He is 18 years old now...and an objectively decent kit drummer. He has had serious drum lessons for most of that time. He is much better on the drum kit now than I was on the guitar at his age. The point is invest in the lessons. IMO it is your best shot at staying on the journey and actually improving (which is funner than not improving) because someone can help you correct your "non-musical" tendencies--and we all have them.
Go get 'em.
