You've been in school for most of the years of your life, and you've been around universities for more years than you may care to count. Teaching can be a very satisfying, rewarding experience. Tenure has its privileges. A tenured professor has the opportunity to embark on risky research without needing to produce short-term results. Interdisciplinary research with university colleagues can be stimulating and fun.
Flexible hours can be a great asset in juggling family commitments.
The first year teaching as an assistant professor can be quite a shock. Almost all beginning teachers devote a tremendous amount of time to class preparation. This eases with experience, but initially it can be overwhelming. Luckily, if your new school can't provide all of this, you can rely on your advisor and other faculty from your graduate institution. In a good department, senior faculty treats junior faculty as full colleagues.
