But the fact is that one can not access these opportunities that the year holds for everyone without a proper preparation and self development which will position each and everyone in a good place so that these opportunities can meet us
One resolution everyone should add to their list is to be more aggressive with achieving personal growth.
Not the habits though but the mentality, if we are still thinking that it's hard to make money in today's time, then that's what going to stick with you. But if you believed that 2025 will be different because you are going to change your thoughts and align everything with your goals and what you feel, then most likely you will see everything manifested int the physical sense.
And there are still plenty of ways to make money just like what the OP says, could be trial and error. But if you go and pursue and again believed that you can make a big change then go for it. Like in crypto or Bitcoin investment, if you say that you are going to do DCA and accumulate and HODL and wait continue to do it for the rest of the year and then just sell and time the market to make profits, then that is possible.
