Moto - give up the toys that your dad bought you. Give it all back to him, that's why you're feeling down, I bet. You're taking but you still want to go riding, etc. This is what I'd do, myself.
I'd stop taking support from my dad. This would force me to earn things on my own. When I saw how hard it was to earn these things, I'd begin to learn the lesson that going riding and entertainment are meant for rewards for hard work.
The things that I earned would have more meaning to me. I would value them more, over the things that were just given to me.
I didn't take a penny from my folks when I was in college. It was hard! I lived on Top Ramen and bologna for so long! I worked. I got a 3.86GPA. There were times when I had to walk to class...uphill both ways.
Seriously, though...the only way to let someone down is to allow them to expect things from you that you don't expect from yourself.
If I was you, I'd show my dad how sorry I was by proving to him that I could be the best at what I'm doing.
It's hard, it's not easy...but it makes you feel fulfilled at the end. Like you were using all of the abilities that God has given you to accomplish something important for His glory.
God bless you, buddy!
