Often, many of us forget how blessed we truly are. A reminder for yourself is to "count your blessings not your problems."
"I will never forget you. See upon the palms of my hand. I have written your name." (Isaiah 49:16) This is a promise Gods made. He hasn't forgot you. He's preparing something better than you can imagine. He's handpicked someone just for you. He has chosen someone that will help you grow closer to Him. He will always be faithful to you.
"Give all your worries and cares to God, for He cares for you." (1 Peter 5:7) When we go through hard times, it's easy to get discouraged and lose hope. I am guilty of worrying about things, who isn't? I over worry everything, but I have come to realize that we must give all our worries to God. Sometimes we don't get what we want, so we assume God hasn't heard our prayer, but God is always listening. There is never a prayer that goes unanswered.
God has plans for you, Jeremiah 29:1 says, "For I know the plans I have for you" declares The Lord, "plans to prosper you and not to harm you, plans to give you a hope and a future." Gods plan may not always be clear, but God has a plan for your life that exceeds anything that you could have ever planned. Trust God, he has a perfect plan. Don't go thinking about what all could go wrong, instead think about everything that could go right. Negativity is a poison that drains your mind.
Main thing: having a positive outlook on life by surrounding yourself with the right people.
