My mom would always remind us (dad, my brothers and I) to encourage and appreciate each other, to find even one single simple thing that we can appreciate from that person before we nicely approach them about their mistake. Honestly, it sounds funny and it's not that easy to do. It takes a lot of self-control to hold your tongue to not to insult and criticize other people, more so to say something nice about them when they do you wrong but it actually works; you can get your message across easier and this way the other person will feel your concern. That person's confidence will be renewed and what you had projected that they are will be instilled to them.
In terms of my journey as a Christian, at times when I stumble, feel discouraged and down, I strive my best to surround my self with other believers and read more about how God had touched other peoples lives. In Romans 1:11-12, Paul said "I long to see you, . . . that I may be encouraged together with you by the mutual faith both of you and me." Surely it feels like you're dragging yourself to go to church, to worship and thank God despite of your troubles but it's an effective way to rekindle your faith and passion. I believe that it's just the enemy's work to make me feel bad and definitely I won't let it win.
Say it; use it more often, you'll be glad you did.
