SEs - how do you manage travel and family?

I recently accepted a Lead Specialist SE role within Salesforce. The hiring manager warned me of frequent travel within the country and hectic workload.

While I am excited about the role and I think I will do really well in a techno-functional role like this - and don't have any immediate responsibilities - how can I best manage travel and future family obligations - motherhood, children, parenting etc in the longer run?
