There is a classic perspective worth pondering: truly skilled investors, when looking back at their lifetime of operations, find that 90% of their efforts were wasted.

The ones who ultimately make money usually rely on just two or three decisions — finding a few good projects and holding onto them, and that's it. Many people feel this isn't right; investing shouldn't be so simple, but the harsh reality is just that.

How to judge if a project is worth heavy investment? First, look at the product itself. Don't be fooled by flashy concepts; return to the most fundamental question — what problem does this solve? Is there a real demand? The most straightforward approach is often the most effective.

Honestly, you don't need to hold many positions. Heavy investment in just three projects is enough, especially those with ample cash flow and long-term potential. The focus isn't on quantity but on truly understanding and trusting them.

There is a special aspect to investing: the later you go, the more advantage you have. Capital snowballs, and so does experience. But the prerequisite is that you must truly hold onto your investments. Avoid buying things just to flip for a quick profit. If you've bought in, think carefully — is this something I am willing to hold long-term, even pass on to the next generation?

The most easily wasted resource is actually time. The market noise is so loud, and there are new things every day, but only a few operations are truly important. You need the discipline to leave things alone and shift your energy to other parts of life. Doing less can actually lead to better results.

Ask yourself: which project do I want to bet my future decades of fate on? When the answer is clear, other options will naturally fade away. That is the most efficient state of investing.
