1. accusers - one who accuses others for his failures
2. excusers - one who always finds excuses on his failures
3. choosers - one who chooses to make his failures as opportunity to learn and grow
You can blame whoever you like for whatever reason you want ... fabricate all the excuses you can think of... but does that solve the real issue? If you still don't get it, listen to this:
"Bury a person in snows of Valley Forge, and you have a George Washington. Raise him in abject poverty, and you have an Abraham Lincoln. Strike him down with infantile paralysis, and he becomes a Franklin D. Roosevelt. Burn him so severely that the doctors say he will never walk again, and you have Glenn Cunningham, who set the world’s one-mile record in 1934. Have him or her born black in a society filled with racial discrimination, and you have Washington Carver, or a Martin Luther King, Jr. Call him a slow learner and retarded-writing him off as uneducable, and you have an Albert Einstein.”
(Quoted in "Developing the Leader Within You" by John Maxwell, 1993)
Reading this quote doesn't give you any right to make an excuse, but if you still have one... look around you and I'm sure you'll find a person more miserable than you...
