There are two major things that effect your building ability: Skill and Natural ability.
Skill:This is the one that can really improve. It involves learning how different block configerations work, and knowing how to use them to make what you want.
Inborn Ability: This one is tricky. As its name implies, you get in naturally. As you mature, your ability will grow to its full and then your kinda stuck with what God gave you, BUT, you can work on improving it, though it will only improve by a small amount.
Example: Sprinting. Someone born with faster muscles is naturally a good sprinter. Someone with slow muscles is naturally slower, but with practice to gain skill, you can run as fast as a naturally fast runner. The exception is that if the naterally faster person gains skill, then they can far outpass those with naterually less ability. These people are those who, for example, go to the olympics.
