assuming that he's someone around my age (late twenties) and that none of these are extreme:

Has difficulty in knowing what he wants, often looks to others for input. i could probably shrug this off, so long as neither are extreme (as in, he's completely helpless on his own). i'd hope that he had at least a general idea of what he wants, though. if that's not even there, then it's more of a negative thing.

Apathetic, doesn't have strong intentions or desires. negative.

Gives up on goals if they take too much time or effort. negative. even if you need to modify a goal because of this, i don't think you necessarily need to give up.

Cowers or doesn't stand up for himself if people disrespect him. negative. i'd feel pretty bad for the guy though. i don't think you need to go around punching everyone who looks at you sideways; there are diplomatic ways of dealing with this, but this isn't great.

Becomes paranoid if obstacles or challenges arise. only okay occasionally. if it's persistent or long term, no.

Likes order and planning, always predictable. predictable sounds a little dull, but it could be alright. i'll go benefit-of-the-doubt and say positive.

Minimizes or doesn't feel good about what he accomplishes. not good. he doesn't need to be super braggy, but he should be able to feel and show some pride when he achieves something.
