The best time to start investing is today.

Whether I have £500 or £50,000, it’s not about the amount but how wisely I allocate it. The key to success is starting early and staying consistent.

Investing £200 a month over 40 years, with an average annual return of 10%, could grow to around £1.3m. A 10% annual return is a reasonable expectation based on the historical performance of the S&P 500, America’s most-tracked index of its largest 500 companies.

Pound-cost averaging

When I started investing, I found pound-cost averaging to be the most effective method for me. I invest a small amount of disposable income from each paycheque into top companies every month, regardless of their current valuation.

As long as these businesses have solid long-term prospects, I keep buying over the years. It’s a simple and reliable approach to building wealth.

One key principle I stick to is diversification. I spread my investments across different businesses to avoid having all my money tied up in just one, reducing the risk of any single company’s downturn.

Getting started

It couldn’t be easier to begin. First of all, I need a Stocks and Shares ISA or a share-dealing account. The provider I’m most fond of is Interactive Investor.

Then, I need a way to source good investments. Thankfully, The Motley Fool UK has this covered, with a range of services and writers identifying top investments every day.

One company I see as a strong long-term investment for pound-cost averaging is Games Workshop (LSE:GAW). This seemingly modest fantasy wargame miniatures developer has grown an impressive 1,600% in price over the last 10 years. On top of that, it offers a healthy 3.5% dividend yield, putting cash in my pocket every year. Bear in mind, though, that management can cut the dividend if market conditions require it.

Analysts expect the company’s earnings growth to slow down over the next few years. But this could actually be a great time to buy, as the current valuation looks reasonable. If its earnings growth picks up again, the stock could see significant gains, and by getting in early, I’d be well-positioned to benefit.

However, every investment comes with risks. Games Workshop has already well-established itself in Western markets, so the company is now looking overseas for growth. Any challenges it faces in expanding into new regions could limit future share price gains over the long term.

Staying the course

I’ve found that one of the best ways to generate strong portfolio profits is by being part of a solid community of investors. That’s one of the main reasons why I appreciate The Motley Fool UK.

More than anything, investing is a lifelong skill. It takes time, patience, and perseverance to build wealth. Developing a successful portfolio is far from a get-rich-quick scheme, and that’s exactly why it works.

As I mentioned, if I invest £200 per month from scratch, I could grow a portfolio worth £1.3m in 40 years, assuming a 10% annual return. Wealth isn’t about luck, it’s about knowledge, preparation, and time spent in the market.
