Do you blame you parents for not letting you learn piano when you're young? Or you parents did not enroll you into piano lessons.
From what I know, the best timing to learn piano is when you're young(4 year old to 11 year old). That's because the neuro-connection of a young child is twice of an adult. Which means to say, young child have the ability to learn things faster and better.
Once you've past the puberty stage, the neurons in the brain will undergo a process which closes connections that are not in frequent use. Hence after puberty stage, you'll find it quite hard to learn piano.
For me, sometimes I'll feel very regret because my parents didn't enroll me into any musical lessons when I'm young. Or maybe is because my house financial is not very good, can't afford for piano lessons.

If only they could develop my talent for piano at that time, perhaps now I am already a good pianist already.
But I do play musical instruments like trumpet when I am in primary school.
