Let's run through the numbers really quick. One student is worth $140 a month...that means 10 students is 5 hours of your time a week. That would add $1400 a month to your income! Nothing to shake a stick at! If you have a full-time job, can you dedicate 5 hours on the weekend to teaching guitar? Maybe that could look like 3 hours on Saturday and 2 hours on Sunday.
This is where it all began with me. I had a job...I worked full-time. I was looking for a way out and this is where it started.
Dial in your schedule and tell me what availability you have. Is it a couple days during the week or is it only on the weekends?
You have an opportunity to give yourself a raise. Start small. 1 or 2 students could mean paying the electric bill, paying your phone bill, or investing that into the stock market. (That's what I've done) Compounding interest is a beautiful thing!
Whatever your situation...are you going to let those negative thoughts dictate what you do with your free time? Insanity is doing the same thing over and over and expecting different results. Now is the time to change that!
Go through the free training. Take action. Comment in the community what you are doing. I never ask for anything. I want to see musicians thrive with the knowledge they have. Good luck!
