Horrors of past investments continue to haunt me despite telling myself that it's part and parcel of my investment journey. One lesson that I can never forget till this day was the missed oppprtunity to sell my blackberry shares. I had bought it initially after reading so much into what the company is doing and at one point in time, I had so much conviction in the company. Then the craze (during GameStop run) happened with share price being pumped up till I was at $27k profit. I was contemplating if I should sell immediately. Everyone was encouraging me to sell to actualise the profit made. I was conflicted since my goal was to invest long term and not just take the profit and go. So I held on to the stock and guess what... it subsequently plunged and it is where it is now. So am in the red, still holding on. 

Lesson learned. So with NVIDIA, I became decisive and took profit early. If I had waited for a few more days, I could have earned a bigger sum but one can never be too greedy. 

I am still a long term investor with more than 5 years horizon. But if opportunities to take some profit off the table present themselves, I have learned to be less greedy and just take some off first. 

Moral of the story: when the winds change, do not hold on to the sail but learn to change the direction to let the wind propel the sail. Never hold on to the sail too tightly lest the rope will snap.
