This is germane, but not necessarily directed at you - it's just a reminder:
If you can't stick to your plan while validating, then don't validate.
It might seem cold, harsh, and closed off, but you ought to have a long-term plan in place and you ought to do everything in your power to set that plan up for success. Validation is a great tool, but it should not be allowed to compromise a larger goal.
