You can believe in whatever you want. You didn't ask us to evaluate your beliefs.
You asked about improving mining profitability on a laptop. But did you even try to estimate the earnings? How much do you expect to make over the next year?
Either way, I can give you the best answer you can get: don't do it - you won't make money.
As for the philosophical part:
If you believe cryptocurrencies are the future, learn to code and the essential math - become a blockchain developer or something like that.
Or look for a blockchain-related job in other role. Or invest in a blockchain company. Or just buy crypto and hope for an appreciation. Etc.
If you really want to mine, you can try that as well. But not on a single GPU and clearly not on a notebook...
