Every day is a new high, just that the gains have been too fast, and I didn't buy enough of a position, but it's still okay.

My US stock account operation principle is that even individual stocks I'm very bullish on can't exceed 10% of my position; I'm just short by 2%.
I operate two accounts myself, one with Interactive Brokers which is my long-term account and I don't do short-term trading; the other is Futubull, which I only use for short-term operations.
Then my long-term account will allocate 50% of the position to regular index investing, and the remaining 50% will select 5-10 individual stocks that I'm bullish on for purchase; if there are no stocks I like, I'll just wait.
My short-term account uses Futubull. I've bought two individual stocks so far, one CRCL has already been sold (very small position, made just enough for a meal), and one RKLB (larger position and continuously adding). When positive catalysts for the commercial space sector materialize, I'll recover my principal and then transfer all remaining RKLB profits to Interactive Brokers, converting it to long-term RKLB holdings. It doesn't matter anyway since it's all profits.
Going forward, I want to do this: whenever a short-term position makes money, I'll recover the principal and some profits, then transfer all remaining positions to long-term holdings. By the time I'm 40, I wonder if I can accumulate 30-50 individual stocks with zero-cost positions. If the stocks keep rising, I'll gradually sell them and increase my index position.
