My thoughts

Don't get married too early. Experience enough to figure out what you want. People are usually mature by 30 and stablize  their career by 35. So Getting married between 30 to 35 is a good choice. Say you got married at 25 and one partner progresses a lot faster career wise than the other partner the marriage will not stable. The two has to grow together if married early and that is very hard thing to do. You would not have this issue if you get married later.
