Really engage with people because you never know what might happen. There is no better time that the present to have a good time and show people that you really care about them. You also never really know what someone else is going through so if you can brighten their day for a moment then you could have a drastic impact on their life.
Showing people that you care about them and give them unconditional love never runs out of style. Sometime you can’t do everything or they are not willing to break down their barriers but that should not stop you from being you and being a wonderful person.
Be as grateful as you can be for anything that someone does for you. Show them how much it means to you that they have spent their time and effort doing something for you. Compliment them on everything they are good at and try to return the favor.
