I would strongly encourage anyone starting down the road to adoption to really evaluate why you are taking this step. Make sure you know what you are planning on.
What do you hope to get out of this?
How do you want things to be in 10, 20, 30, or 50 years?
What will you do if things turn out as you expect?
What will you do if they turn out differently?
The adoption route is not "just the same as giving birth to children. While it may seem like you are picking your children, you will almost certainly end up with a lot less input on this than you think and you will likely end up with a lot different child than you may expect up front.
These questions don't have a right or wrong answer (at least none that I am going to cover now), but they are worth some time to think deeply on before you proceed.
