I know the feeling. Stings to feel like you left something on the table. But focus on the fact that at least you made a move and put something out there. Was a good decision. The $ you make will still have the power to help you build a great portfolio/life
You are fortunate to have as many as you do. There are thousands of people who would love to be in your situation. They'll be chasing it next week and the week after to get as many shares as they can, but their cost will be way over yours. Congrats on buying early. We still haven't seen the big run up. This is just peanuts.
