Need suggestions and opinion

My investment period is 20-25 years, after which I'll switch to a Systematic Withdrawal Plan (SWP). I also plan to make lump sum investments when the market is down. Since I'm just 19 years old, I have an aggressive risk appetite and want to invest for the long term. I started a SIP last February with ₹3,000 per month, and I plan to gradually increase this amount as I start earning more. I also have a stock portfolio worth ₹25,000, which I intend to grow over time. Should I stick to this strategy, or should I make any changes? I'm open to starting 1-2 more SIPs in the future. Feel free to share your suggestions and opinions for this new investor.
