So I am just basically setting myself up for failure and disappointment then? I have such a strong desire to get my music fully produced and to get it out there in the world to get it recognized,
What music? According to you, you haven't made any music. Ever. There is no such thing as wanting to get your music out there when your music doesn't exist. Wanting to have music to get out there? Sure. You can definitely want that. But unless you sit down and actually produce some music, you may as well be saying I want to show the world my magic purple unicorn that poops flying t-bone steaks.
As for not being sure whether or not to try because it might be pointless if you fail? Well I let you in a couple little secrets.
Secret #1: Its all pointless.
You have never existed here before. You will never exist here again. You could sit on your duff and eat corn chips until you die or you could invent the next generation of electronic instruments and either way in 100 years you'll be long since dead and no one will know your name nor anything about who you were nor what you did.
Secret #2: When its all said and done, you're not going to care whether you achieved fame or not.
Here's the thing. We're all going to die and none of us know when that will happen. So your heart condition doesn't change anything as far as deciding what to try or not try. Any one of us could get hit by a bus tomorrow, just like you. If we all allowed that to dictate what did or did not try, none of us would ever try anything.
So lets say you decide to go for it and try. And lets say you never realize any kind of fame for you effort. In the end, you're not going to care.
Here's the bottom line. Its a pointless ride. Your only job is to enjoy it. So if you think you would enjoy the process of learning to make music and then enjoy the process of making music, then you should make music. If on the other hand, the only thing you would truly enjoy is fame and recognition, then I highly recommend you consider shooting a sitting president*. Because that is the only thing that will give the vast majority of us any shot at any kind of fame. Even mass murder is common place now and so no longer awards the perpetrator any sort of lasting name recognition. I defy you to name even one mass murderer from the last 24 months without the use of google. If you want guaranteed fame these days, you gotta shoot a president.* That's about the only way.
