When I was 16, my parents took me to the store to buy my first "real" guitar.
I had one that a friend gave me, but it was of the homemade, Frankenstein variety. I picked a shiny red humbucker equipped beauty (of the $200 dollar variety and I had to pay for half of it! It was likely all the money I had saved).
That guitar had so much possibility built into it. I could hear the rocking chords on the way home from buying it that would pour out of it once I plugged it into my 10 inch beast of a Sears amp once I got home.
I got home and, once I got to my room alone, put it in my lap to play (I hadn't stood up w a strap to play at that point)...
Rocking chords? Enchanting melodies? Nope. Instead I realized that it was shaped too funny to sit in my lap. The other guitar sat neatly in place - this guitar kept sliding out of my lap when I tried to hold it.
In a bout of frustration, I did the unthinkable- I slammed that sucker on the floor. I had intended to break it I was so mad. Fortunately for me, $200 guitars are a little tougher than that.
I cried. I left the room. I came back. And then I did what I bet is the same thing that you have done at some point in your life.
I picked the damn thing back up and tried again.
And a million times since then, I have proverbially thrown my musical guitar across the room. Cried. Left. Came back. Wash, rinse, repeat. But I've never abandoned my dream to write and/or perform music.
If you're not that passionate about these hobbies for which you read blog posts to gather new inspiration, I am willing to bet that hobby just ain't that important to you. If, on the other hand, you are reading this during your break away from that '@$!)& thing that I just can't seem to do right!!' – it's okay. Don't give up.
P.S. - Unfortunately, while $200 guitars are tough, they can only be dropped so many times. It had a good tenure as my primary axe for about 12 years. I've since learned to throw cheaper things. :)
