Do you eliminate saying “please” at the end of phrases to avoid sounding desperate?

Is it appropriate if I use interrogative terms that are pleading such as please?, will you?, how about this and that? in cases where I am in serious need of proper help. I do not want to appear as vulnerable so others could take it as my weakness. Without losing my dignity, how can I ask for an advise with the purpose of improving myself for the next time and being educated about a certain thing I am not aware of?
