The best thing you can do is understand the game well, and build well within your means. Strive to work smarter, not harder. Make a priority list and stick to it like the law. Have fun. Keep organised.
Do these things and the rest will come. Don’t jump too far into the practice robot camp before you seriously evaluate not only your financial situation (the thing that everyone things about) but your ability to actually make that second robot during the season (the thing that few people talk about). I have seen far too many teams have “practice robots” that the team is too busy fixing/getting ready/building two robots at a time that no practicing actually gets done. Not only do they not practice, it hinders the competition robot as less time is devoted to it. Be very careful with them. That being said, if you can do it, it’s a huge asset.
