general tips
Imposter workaholics are actually addicted to the validation that comes from working, not to the work itself. Start training yourself to veer away from external validation. No one should have more power to make you feel good about yourself than you–-even your boss when they give your project the stamp of approval.
On the flip side, learn to take constructive criticism at face value, not personally.
As you become more attuned to internal validation and able to nurture your inner confidence, affirming that you are competent and skilled. You'll be able to ease off the gas as you gauge how much work is healthy and rewarding.
