Getting a date can be difficult, especially if you have a busy work schedule. However, it is not impossible. Finding a person to spend your time with might just take a little work. First, you might want to consider whether you are really ready for a relationship. Do you have enough spare time to spend with the other person, or are you hoping that the other person's life fits into your schedule? If you identify with the latter, then it might be a good time to put a hold on dating and wait until you have time to dedicate to the relationship.
You might also want to consider whether you are willing to compromise. Compromise can be a big thing in a relationship as it can allow both people to get what they want from the relationship. If you aren't willing to compromise on the things that you want to do or how you spend your time, then it might be a good time to wait on dating.
Also, you might want to consider if you are in the position that you want to be in before committing your time to another person. Are there still personal things that you need to work on to be a better partner? Are you financially stable? What can you bring to the relationship? Getting into a relationship means that you are adding someone else to your life, so you might want to make sure that you are in a position to give as much as you take from the partnership.
Knowing when it is a good time to date can be different for everyone, but it might be good to reflect on the situation before you jump into it. Analyze how much time you have to spend with the other person and think about what you have to give to the relationship. If all flags are green, get out there, and find someone.
