5 Mistake Tips:
1) When bootstrapping your startup -- don't spend money on things you're not sure you'll need or use. There are a lot of software programs and ad platforms out there. You don't need one of everything to get started.
2) Managing a budget: Have a Dollar in, Dollar out mindset.
3) "You get what you pay for." For instance, if you choose the cheapest designer for your brand, don't be mad when it doesn't live up to expectations.
4) You typically need to spend money to make money. So, if you spent $100 on an ad, don't think it's going to generate thousands of sales transactions.
There is no magic bullet. Beware of schemes. And if you're going to spend money on something to acquire customers, make sure it has much credibility generating ROI
5) You don't know what you don't know. It's always good to spend time with a mentor, rather than trying to learn everything by personal experience and/or online trainings.
