Then I shall congratulate you for being well-encouraged and thick skinned in your world already. For everyone else lacking such good fortune, though, it would be nice if we could err on the side of being welcoming, rather than hostile.
Someone helping me with a project is nice. Someone helping you with a project is an investment in the future. My neuroplasticity wanes with every passing year. Your mind remains limber. I am encumbered by obligations and debts, limiting my flexibility. You have infinitely more options.
Helping you is just a better bet than helping me. You're still on the launchpad, fuel tank still full. If there's something simple, like an encouraging comment or a thoughtful correction, that can be done to help you meet a wonderful trajectory, we should absolutely do it.
The world is comprised predominately of people that either 1) don't like you or 2) are indifferent to you but don't like your work. That's not because their assholes, but just because they're aware of the flaws in you or your work. The sooner one experiences them, the sooner one can start to take advantage of their advice.
