The meaning of 'paint you in the best light'?

Please help me explain the meanings of following sentences:

  1. Being at the shoulder of people who are making the decisions is a vastly different story than being in a position to read magazine.
  2. I’m not going to paint you in the best light.

Thank you very much!

  1. Being at the shoulder of people who are making the decisions is a vastly different story than being in a position to read magazine. = Working with decision-makers is much better than reading about decision-making.

  2. I’m not going to paint you in the best light. – I’m not going to present a very good image of you.

Thank you very much, Sir!

Dear Sir!
I have another question as follows:
Does ‘All work and no play makes Jack a dull boy’ has the same meaning with ‘All work and much play’?
Thanks!

That should be pretty obvious, Galilom - ‘no’ means ‘no’ and ‘much’ means ‘a lot of’. They are quite opposite in meaning. In any case, it is a fixed saying.

So 2 above sentences means ‘We should work and rest properly’???

No. I have already said that your idea for changing the sentence is not the same meaning at all.

‘All work and no play makes Jack a dull boy’ does mean, however, that without time off from work, a person becomes both bored and boring. A balance should be reached.
