I believe God's plan is that people are married (even if it doesn't always work out for some). We were made for relationship. And while no-one suggests that marriage is superior, the years of waiting for someone to come into your life can be fruitfully employed to work on your own weaknesses in order to prepare you for who God has for you, or the life God has for you. If you don't believe that self improvement can take place in an individual's life and that we're all just here living from day to day and moment to moment, well then there is nothing I can do for you.
Marriage is not the ultimate goal of life. However, I would rather work on being the best version of myself so that I can sow into someone else's life so if that does happen, I can be who God wants me to be for them.
