This is totally just IMO, but I'm an optimist and I believe almost everyone "has what it takes" to do what they want. Although it may seem intimidating, don't let stupid core stuff like math keep you from trying. If you want it bad enough, don't let anything get in your way! =) However, if you're just not sure because...well...you're just not sure, I have to echo the "picture yourself in the future" sentiment. Sometimes just taking a step back and thinking in terms of "what would make me happy" without considering ANYTHING else can be very revealing. I hope everyone's advice helps, good luck with your decision!
