It will be nice to tell people about bitcoin, but not to force/pressure them to invest , because if investing goes wrong sometimes it is funny to see the reactions of people when money is loss, the loss of money is a case that has ended many good friendship and misunderstanding between family members.
How can one even force another to buy Bitcoin, there is quite a lot of risks inherent in the network that if you do something like that, chances are very high sooner or later you'll be blamed by your 'newly converted' investors when there is a correction/dip/plunge or generally anything that causes them to worry about their funds.
Having said that, research is integral in the Bitcoin network, thus whenever you want to talk to someone about Bitcoin, the best you can do is to provide such individual with materials of different sorts: Books, videos, links etc, for them to go and read about Bitcoin and then make their own personal decision, if they come back to you in the affirmation, then you can go ahead and assist them in Buying their first Bitcoin, pointing out to them which wallet to use or not to use, etc, but the most important point remains that their decision on the network must stem from doing their own personal research, not you trying so hard to convince them. Just as satoshi said:
If you don't believe me or don't get it, I don't have time to try to convince you, sorry.
