How To Avoid Pointless Conversations
1). If the conversation doesn't peak your interest within the first ten (10) seconds then it is time to walk away.
2). If the person is known for wasting your time in the past then they will almost definitely waste your time in the future. This means to avoid him/her.
3). What value does this person bring to your life? This should be very easy to answer. And your next decision should also be equally as easy.
4). Let the person analyze their own reasons for pointless conversations. Ask them what they gain from such nonsense.
5). Be completely direct with the person and let him/her know that their conversations lack substance and you seriously don't appreciate your time being wasted like that.
