Formal alternative for "suck" [closed]

What is a more decent/formal alternative for the word suck? I want to use it in the context of being bad at something.

To be precise, I want to translate "To suck less at a job every day" to formal English.

Solution 1:

I think you just used it. Any alternative is going to depend on exactly where you are using the phrase. A CV will need a different expression from chatting to your mother.

I'm bad at ...
I'm not all that good at ...
I find it difficult to ...
I can't ... for toffee.

If I tried to arrange flowers it would end up looking like a hedge.

To suck less is to improve:

Every day, I want to improve at ...
I'd like to get better at ...
I'm working at becoming more proficient in ...

Solution 2:

You should be more careful because what you're writing is a CV and not just any story.

Basically, what you would like to say is that you suck but you are a "fast-learner."

Like you said, "I suck less at a job every day."

Now, the problem is how to word it because the expression "fast-learner" or "quick-learner" is actually a kind of cliche in CV writing.

You could say:

"Positive attitude with ability to adapt to new challenges."

Or,

"Enthusiastic, knowledge-hungry learner, eager to meet challenges and quickly assimilate new concepts."

Or,

"Succeeded in only _ months to educate myself in _ areas."

The last one is actually an example of how you can "show" and not "tell" that you are indeed a fast-learner.
