This is exactly the attitude that ruins things.

Think of it being like

        I love my dog.   He (or she) is familiar, friendly, and does
        whatever I ask of him/her.   (Substitute cat if you're that kind
        of weirdo!).

        Now I want to play tennis.    Here boy (girl).   Hold onto this
        racquet and hit the ball back.

        Oh, you need hands, well, let's see how I can make that happen....
        You're not tall enough to hit my lobs, well, leg extensions coming 
        up...

Use the right tool for the job at hand, don't try and make every job
fit the tool that you like best.   That is fruitless, and likely to
ruin the tool while you're trying to bend it into the shape you need.
