Just Seeking - Socking It to 'Em

When you enter competition in your favorite activity - a fun poem.

Hard not to love things
You're great at, can do -
You just press some button
And always pull through.

But work has now started,
The ace has begun;
What once was a hobby's
Now more than just fun.

But goals are so lofty,
The merger is bright
Between something and pro,
And you now must stay right.

Adjust to some heartache
And muster belief. 
The challenge made simple;
The goal is relief.
