The Ice Age occurred due to the accumulation of ice over time, not because it was colder than normal, but because we had fewer sun rays in the summer each year; the same situation applies to the accumulation of wealth over time.
The important thing is to have an initial base to compose investments in the long term and to accumulate over time, letting compound interest do its job.
For example, we see Warren Buffett, who started investing at the age of 18 and has been investing for more than three-quarters of a century. Composition gains strength with each moment.
In conclusion, starting and maintaining contributions every month makes the magic happen.
