the meaning of reckless is positive or negative ?

reckless means showing lack of care about danger and possible results of the actions.

Does it mean doing something without thinking twice, not caring what others advices, warnings ?

I’d like to ask does the word carry the negative (= doing it impulsively)/ positive (=dare to do sth) or just neutral meaning (based on the context).

Thank you very much all the teachers, forum moderators for the things you helped and taught us, I have learned so much on this forum since the day I joined. I wish all of you a merry Christmas and happy new year. I hope you have a good time with your family on these special holidays.

Most of the time it carries very clear negative connotations.
