Definitely a good skill to have is to be able to ride up a curb. You can get learn the skills
Russ Roth described just riding around and practicing them individually. Just pull up to get the front wheel up and lean forward, kick back and pull the rear up. These skills come in handy for much more than just riding up a curb, you can use them for getting over a tree branch in your path, road damage, etc. Good luck!
